Phase 2: During this phase some carbs are back, so you have to watch out for any weight gain. (Following the strictness of Phase 1, you might be inclined to overeat your favorite carb-filled foods). You’ll get to eat no more than 50 grams of “good carbs” per day, including whole grains, beans, and fruits. Still, the bulk of your diet will consist of lean proteins, good fats, and vegetables.
"Oolong, or 'black dragon,' is a kind of Chinese tea that's packed with catechins, nutrients that help promote weight loss by boosting your body's ability to metabolize fat. A study in the Chinese Journal of Integrative Medicine found that participants who regularly sipped oolong tea lost a pound a week, without doing anything else to change their diet or exercise habits." — Kelly Choi, author of The 7-Day Flat-Belly Tea Cleanse
It can actually help you cut back on calories. That's because capsaicin, a compound found in jalapeño and cayenne peppers, may (slightly) increase your body's release of stress hormones such as adrenaline, which can speed up your ability to burn calories. What's more, eating hot peppers may help slow you down. You're less likely to wolfed down that plate of spicy spaghetti — and therefore stay more mindful of when you're full. Some great adds besides hot peppers: ginger and turmeric.
Forget old low-carb diet plans that focused on processed protein bars and shakes. This year, the keto diet got high marks for low carb. Keto, short for "ketogenic," is all about training the body to burn fat for fuel. How? By eating fat—and lots of it. Most keto diets recommend getting at least 70 percent of your daily calories from fat and the rest from protein. The goal is to eat as few carbohydrates as possible. Proponents say it helps them drop weight fast with little or no hunger in addition to perks like more energy and mental clarity. (Interested? Here's everything you need to know about the keto diet.)
Still, it’s a worthy goal to lose belly fat because it’s “unfortunately the most dangerous location to store fat,” says Lawrence Cheskin, MD, chair of the department of nutrition and food studies at George Mason University and director of the Johns Hopkins Weight Management Center. Because belly fat—also known as visceral fat, or the deep abdominal fat that surrounds your organs—is more temporary, it circulates throughout the bloodstream more regularly and is therefore likelier to raise the amount of fat in your blood, increasing your blood sugar levels and putting you at a greater risk of heart disease and type 2 diabetes.
Not much of a coffee drinker? Tea is also a natural diuretic, and types of herbal tea such as dandelion or fennel root can also lend a hand. In fact: When a recent study compared the metabolic effect of green tea (in extract) with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period.
Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
Aim to get at least seven hours of sleep each night. Try going to bed and waking up at the same time each day. Why? Ever notice how you start to crave donuts and drive-thru breakfasts when you’re exhausted? When you don’t get enough sleep, your hormones are thrown out of balance. Running on no sleep can actually drive up the hormones that make you want to eat, while pushing down the hormones that signal for fullness—and that’s a recipe for weight gain. When you’re well-rested, it’s much easier to make healthy decisions and stay on track.
It's a one-time investment you'll never regret. Here's why: Strength training builds lean muscle tissue, which burns more calories — at work or at rest — 24 hours a day, seven days a week. The more lean muscle you have, the faster you'll slim down. How do you start strength training? Try some push-ups or a few squats or lunges. Use your free weights to perform simple bicep curls or tricep pulls right in your home or office. Do these exercises three to four times per week, and you'll soon see a rapid improvement.
To prep his patients for success, Dr. Seltzer tells them to plan around a large evening meal by eating a lighter breakfast and lunch—NBD since most people who eat a meal before bed tend to wake up feeling relatively full, he says. Research suggests balanced bedtime meals may also promote steady next-day blood sugar levels, which also helps with appetite regulation.
If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
Variety: Nobody wants to eat the same thing day in and day out. That's why a variety of food items is essential for a diet plan to be sustainable. Also, variety as a criterion for determining the best diet plans refers not only to food items but also to groups of people. For example: Is the diet plan available to diabetics? Men? Women? People with allergies or special conditions?
The fad military diet consists of low-calorie, odd food pairings such as bun-less hot dogs with banana, carrots, and broccoli. “Any diet like the military diet that severely limits the amount of calories you consume or eliminates one or more entire food groups puts any individual at risk for nutrient deficiencies,” says Kyle. “This can be more harmful than holding onto those 10 extra lb you’re trying to lose.” (32)
"The American Heart Association recommends that men eat less than 36 grams of added sugar and that women consume less than 24 grams. However, for optimal weight loss, I tell my male clients to consume less than 20 grams of sugar per day and I tell the women to consume less than 15 grams. The easiest way to cut back on the sweet stuff is by consuming less sugary drinks and dressings. Cut the sugar, lose the fat, regain your health and life." — Dr. Sean M. Wells, DPT, PT, OCS, ATC/L, CSCS
"If weight loss is the goal, I recommend learning how to properly deadlift. Deadlifting recruits more muscle fiber at once than any other exercise. More muscle working equates to more blood flow, an increased heart rate, more metabolic demand and output. It's compound, multi-joint and more bang for your buck, not to mention you'll develop an excellent posterior from them." — Victoria Viola, PN Certified Nutrition Coach, NSCA CPT, Co-Founder, Excelerate Wellness, LLC
